Apple is in the middle of evaluating potential parts for the next-generation iPhone, according to a Barclays research memo. One expected choice is Qualcomm's MDM9615 chipset, which enables voice and data over LTE. The part is different from the MDM9600 used in the third-generation iPad, which is limited to data only. It also remains to be seen if the new iPhone will support "world" LTE, unlike the iPad, which requires different models for different bands. Adding LTE to the iPhone is expected to cost Apple between $3 and $10 extra per unit versus 3G.
